The hydrogen fueling dispenser nozzle could not be completely disconnected from the vehicle after refueling. It was finally disconnected after trying several times. The cover of the nozzle interfered with the disconnection operation. No malfunction of the nozzle was found. It can be easily disconnected when it is withdrawn along its axis. Sometimes misalignment occurred due to the weight of the dispenser hose.

Lessons Learned

Manuals showing the correct connecting and disconnecting procedures were established for each fueling dispenser. Separate manuals were needed since the shape of the grip differs from dispenser to dispenser.
